BLASTED ON GLASS.
SECRETS OF A PROCESS OF WHICH
LITTLE IS KNOWN.

An Art Manufacture In Which Chicago
Occupie, "a Prominent Piace--Chst With
a sand Blast Man-Naking Rub"
Another Process.
A costly folding bed stood in the front
hall Of n mansion on Washington boule-
ward The furniture men had just left IL
and had returned 10 the store 10 secure
the additional help required to handle II.
The lady Of the house had callers in the
parlor who rose TO 20 before the furniture
| handlers returned Ii was an elegant
bed. and as the ladies passed TO admire 1t
| the mistress pulled the gilded handle at
the side. and the couch magically unyoked
itself from the perpendicular part and
slowly descended. The good lady had
intended 20 show her friends how easily
il worked, but had miscalculated the dis
lance between the bed and the inner
| lights OF the vestioule door. Result,
crash. half a bushel of fragments Of deco
rated glass, and a $50 job for the SAND
blast man. The smashed dOOrlight had
borne an original design, the central figure
being monogram formed by the initials
OF the name Of the master Of the house.
The glass had been set for three years,
and when the sand blast man ascertained
this he turned 10 his books and found this
entry:
peter Wintringham, rub, Sept 4,
1884, folio 9, page l52. '
lie touched an electric bell, had folio 0
brought in, in which, at page 1872, he
found proof Of Peter Nottingham
door lights. On the proof was the legend:
Stencil 1854 He touched another cleo
trio bell: TO the workman who answered it
he said: duplicate 9.SGi, " and Peter
Wintringhams vesti5ule presented its
normal appearance the following week.
HOW TO MAKE A "RUB
Before the sand blaster sent the lights 10
Wintringham' residence in 1894, he made
rub Of them, and this IS how il is
done:
Put a piece Of paper on the glass you
wish 10 get the pattern from, and rub the
paper with piece Of "heelballn such as
is commonly used 10y shoemakers. The
paper must be held firmly in its place. so
a. not TO slip, if you wish 10 get a correct
copy If necessary, get assistance IN hold

What is sand blastingi" asked the
writer Of "A Chicago man whose life has
been spent In decorating glass. The
grinding or decorating OF glass with sand
IA secret process. the inside facts of
which we cannot disclose Come up stairs
and see a sand blast machine The ma
chine suggests cider mill in shape OF a
cheese press At any rate it's a novel
creation. which tine artist faithfully rep
resents. The glass is laid on rubber belts
at the side and rs then fed into the ma
chine As soon as 10 disappears from
view some rubber flaps come down and
prevent the pressure in the interior from
escaping This pressure is eXerted by
wind and sand-a twenty horse power
engine being required TO raise the elbow"
which drives the sand TO the glass Look
ing through the window in the center II
the machine "grn" is disclosed. 1t has
a large, mouth shaped opening, at which
it is loaded with twenty horse power am
munition OF wind and sand. Before the
ammunition is allowed TO leave the gun
the aperture narrows to about one-siXtb
the width Of the loading point. This con
denses the sand so that when 10 leaves the
gun 10 strikes the glass with such force
as 10 eat into the surface. When the glass
has been thus exposed it passes out OF the
machine on rubber belts at the opposite
side This process is called grinding, and
one machine will grind about 600 square
feet il Il day.
THE DECORATIVE PART.
Now for the decorative part Suppose
the sandblaster wishes to present on
. ..f... f..f. 4 afr
ply covers the surface with beeswaX and
a certain mixture laid on over the glass
in exact duplicate Of the design desired.
The glass passes into the machine. The
sand is fired from the gun, but this time
it grinds only the exposed parts The
portion covered with beeswax and the
secret mixture is not touched by the sand,
and when the plate emerges from the
machine end She wax, etc. are washed
Off. behold the design standing out IN
sharp contrast 10 the ground surface
which the sand has scarihcd.
This is the & b of sand blasting The
process is susceptibleof much elaboration,
and one improvement, which was patented
| last year by a Chicago gentleman. Is called
the "Ammograph The pictures are first
/ drawn on the back Of the glass by the
artist with a color which viii resist the
action of the sand blast. II Is then sub
iected 10 the stream of sand, which cuts
the glass in all parts which are not covered
more or less by the resistant The resist
ant is then washed off clean, leaving the
pictures cut into the glass They are next
| siyered over. if desired, 10 give greater
bmlliancy The effect is that of multi
plicity of colors. but no paint OF colorIng
IF any Kind is used, the effect being OBJ
aimed by the different shades Of the glass
